As you can see there is a lot of liquid that assembles at the sides. This lasagne has bechamel and marinara sauce. The bechamel is reduced, with a chunky (but watery) red sauce. The lasagne pages were boiled and drained (but not pat dried).
What could be done to reduce the liquidity of the lasagne and make it more gooey and stable?
